11 and said operating lever 11 is connected with the closet through the bracket 12 and pivotal bolt 13. The lever 11 is also pivo'tally connected with the vertically moving rod lhthrough the bracket 15 and pivotal bolt '16,' andthe upper end of therod le is rigidly ailiXed to the sliding member 16 by a threaded bearing 17 and said member 16 is slidably supported from the tank 4within a sleeve 18.

19 is -a collar, which is rigidly ailrxed to the rod 1i.'

v20 isa spiral spring, which is interposed between the l the lower side of the ,sleevev 18, vwhereby as the rod 14 is raised'by the downward pressure upon the seat, said spring will be com'- pressed, and whereby as soon as the pressure upon the seat is will bevforced down by the recoil of said Spring.

Motion communicated from the slidable member, 16l to the flushing valve, 26,

vupper side of the collar 1S) and removed, said rod 14 through the swinging member 21, lever 25,

andlinks 28 and 29. The member 21 is pivotally supported from said slidable member 16', uponthebolt22. The member 21 `is provided 'with' a rearwardly extendingrlug 21 which is adapted to bear against the right hand side ot' the sleeve 12S, reference beingjhad'to Fig. 2 ot the drawings, whereby said member'21 is prevented from swinging toward thele'ftas it is moved downwardlyfin contact with the short arm '21 of the le`ver'25. l v

It will now ybe understood Y that when downward pressure is applied to? the seat,

an upward'movement willl be communicated to the member 21 through the intermediate mechanism described, whereby the lower end 'i V23 of the member 21 is raised land caused to swing of its-'Own gravity abovevthesliort arm 24 ofthe` lever 25, whereby as soon as downward Vpressure upon the seat is relieved, the lever 21 will be brought'into contact vwith the end Aof the-short arm 24 ofv 'Saidi lever.

y Said short arm will. be forced down' by the re-coilQof said spring 20, acting the `flushing valve126. vwill be quickly raised,

combination with the mechanism herein described for automatically opening said valve, consisting inl the combination of a two armed lever for raising saidvalvefthe arms of which lever are of unequal lengths, a swinging member ivotally supported above the short arm oil:J said lever avertically sliding .member upon which said swinging arm is mounted a sleeve inclosing said sliding member, a rearwardly extending lug formed in connection with said swinging member and adapted to bear against one side of the inclosing sleeve of said vertical sliding member, the long arm of said lever being connected with said valve, a seat pivotally connected with said closet, means for communicating motion from said seat to and for raising said swinging member as a downward pressure is comn municated to said seat, a spring for/forcing lsaid swinging member down upon the short armA of said lever as the downward pressure `upon saidV seat is removed, whereby saidV valve is raised and the contents of said tank Vis discharged into said closet.

In testimony whereof I affix my signature in the presenceof two witnesses.
